Since 1991, the National Intelligent Transportation Systems (ITS) Program has pursued research, technology development, and field testing and has promoted deployment of first-generation ITS applications. The program can be divided into six broad areas of interest: enabling research, advanced metropolitan travel management systems, advanced rural transportation systems, commercial vehicle operations, advanced collision-avoidance and vehicle safety systems, and automated highway systems. The program has demonstrated that the ITS concept, even at this early stage, is technically viable, highly cost-effective, and increasingly accepted as an essential component of a modern surface transportation system. To realize the full long-term potential of ITS, however, an information and communication infrastructure is necessary to ensure that ITS services are integrated, intermodal, and interoperable. Although the full potential of ITS has yet to be realized, enough has been learned in the past 5 years to verify the wisdom of forging ahead, nurturing the National ITS Program, and allowing it to fulfill the Intermodal Surface Transportation Efficiency Act's promise of a safer, more efficient, and less costly intermodal transportation system. A sidebar outlines the guiding principles of the ITS Program. |
